' WELLDBIILLING 'Massima To all. whom 'it may concern:

Be it known thatLfTnoMAs H. Keim, a'

gheny andv State of Pennsylvania,have invented certain new aint'nsefulImproyements in VellfDrilling Machines, otwhich the following is aspecification, reference being .had therein 'to the accompanyingdrawing.

This invention relates to well drilling ma` ehines, and moreparticularlytothat type of machine designed for drillil'lg oil and gaswells.

The primary object of this invention is to provide a drilling machinefor drilling well holes of great depth, the machine being con-V structedwith a positive driving mechanism whereby lost motion is eliminated anda maximum degree of eliiciency obtained with Another object of thisinvention is to provide an oil drilling machine of a portable naturethat can be made permanent at the side of an oil well. whereby themachine can be safely used without subjecting the inaehine to thevibratory stresses and strains set up when the machine is in operation.

A still further object of this invention is to provide an oil drillingmachine with an interchangeable walking beam and spudding mechanism.

lVith the above and other objectsin view which will more readily appearas the invention is better understood, the same consists inthe novelconstruction, combination Aand arrangement of parts to be hereinafter described and then claimed. Referring to the drawings -Figure l is anelevation of a machine constructed in accordance with my invention, themast or derrick thereof being partly broken away, Fig, 2 is a plan ofthe machine with the mast or derrick in horizontal section, Fig. 9 is ant) enlarged side elevation ofthe chain drive forming part of themachine, Fig. 4 is a plan of the same, F ig. 5 is an enlarged front elelvation of a tension device for the walking beam of the machine, and Fig.G is a side elevation of the same.

Referring to the drawings in detail, the reference characters -1 and 2designate longitudinally extending bars and the reference bars togetherforming thereby a frame rectangular in contour and constituta-Xle 8, thelatter serial'no.' 484,419.5

ing'the body-portion of themach'ine. Y The "body-gordon isv supportedi1-pon the holsters 6 and the l*former being carried by the rear beingprovided with Wheels 9. The-front of the axl fifth wheel 10 and thereonthe 'front being providedwith a further has mounted Wheels l2.

13 designates an engine of the ordinary and Well known type which issupported upon the bars 3 and 4 for driving a crank shaft 14 journaledin bearings 15 mounted upon the barsA l and 2.

16 designates a balance Wheel carried by the crank shaft 14 adjacent tothe bar, While 17 designates a flanged sprocket wheel carlia'ied by thecrank shaft 14 adjacent. to the ar 1S designates a sand reel journaledin bearings 19 carried by the bars 1 and 2, said sand reel having abrake wheel 20 contiguous to the bar l, also a small flanged sprocketwheel 21 contiguous to the bar 2.

designates bearings carried by the bars 1 and 2, and insaid bearings isjournaled a shal't Upon the shaft 23 is mounted a reel 24, and slidablymounted upon said shaft.- is a. clutch member 25 adapted to engage -thehub 2G of a gear wheel 27 loosely mounted upon the shaft 23.

28 and 29 designate flanged sprocket wheels carried by the shaft 23adjacent to the bar 2 and over said sprocket wheels and the wheels 17and 21 travel sprocket chains 30 and 31, said chains being of -a typecalculated to provide a positive drive with a minimum amount of lostmotion and energy.

32 designates a clutch mechanism used in connect ion with the sprocketwheel 29, which is loosely mounted upon the shaft 23, whereby said shaftcan be operated independently of the sand reel 1S.

33 designates ascrank carried by the end of the shaft23 adjacent to thefran'le l, said cra-nk having a plurality of openings 34, whereby aWrist pin can be adjustably connected to the crank.

36 designates a shaft journaled in bearings 37 carried by the bars 1 and2, s aid shaft supporting a large drum 38 having one end thereofprovided with a brake Wheel 39, while the opposite end is provided witha large gear wheel .40 adapted to mesh with the gear wheel 27. Inconnection with the e of the'v machine'is, .indicated bythe referencecharacterll and supports the bolster 7, the said front axle l1A brakewheel 39, a brake band 41 is used, said band having one-end thereofsecured to the bar 1, as at 42, while the opposite end is connected to abrake lever 43, pivotally conlare mounted two cranks 48 and 49, thecrank 49 being connected by a pitman 50 to the crank 33, while the crank43 supports a revoluble grooved wheel51 adapted to engage a drillingcable 52 attached to the drum 38. Y

53 designates a samson post carried by the transverse bar 5. Fulcrumedupon the sam-1 son post 53 is an angularly `disposed walking beam 54,the rear end of said walking beam supporting a pitman adapted to beconnected to the crank 33, while the forward end of the walking beamsupports a tension device adapted to be used in connection with a cable52 and a temper screw (noty shown). 56 designates av tee head, of atemper screw frame, said head extending above the forward end of thewalking beam 54. Clamped upon the stem 57 of the temper screw frame is across head 5S adapted to rest in the transverse groove 59 of the walkingbeam 54. The cross headV 58 is provided with two sets of upright guidepins 60, the pins' of each set being vconnected at their upper ends by afixed plate 61 and a movable plate 62, these plates confining the teehead 56 between the pins 60. 1Eincircling said pins between the crosshead 53 and the plate 62 are coil springs 63. 1

64 designates masts erected upon sills 65, said masts being suitablysupported in an upright position by guy-wires (not shown). 66 designatesfoundation sills which are positioned beneath the ends of the bars 1 and2 after the machine has been located, said sills bracing the machine andsupporting the same similar to a separator machine. I prefer to move themachine into specially prepared roads or ditches whereby the bed 0f themcahine will be in proximity to the ground and can be easily braced bythe sills 66.

The elements 58 to 63 inclusive constitute a tension device adapted torelieve all excessive stresses and strains upon the drilling cable 52when the Ysame is in operation. The elements 47 to 51 ingliisiveconstitute a spudding device which Yis used in starting a hole, saidspudding device being generally used for the first twenty-five or fiftyfeet drill. After the hole has reached such a depth, the pitman 50 isdisconnected from the drank 33, and the pitinan 55 connected to saidcrank, whereby the walking beam 54 can bei.oscillated tol raise andlower the drilling cable 52 in the hole previously started by thespudding' device. Through the medium of the elements 13, 32, 25 and 43,the operation of the machine can be easily controlled.

It is thought that the operation and utility of, the machine will belfully understood without further description, .and while in thedrawings forming a part of this application there is illustrated thepreferred enibodiments of my invention, l would have it understood thatthe detail construction thereof can be varied or changed as to shape,

roportien and manner of iassemblagewithout departing from the spirit ofthe invention.
